If the victim has a phone with a hook that presses down
when the handset is in the cradle, tape it down. When he or she answers a
call the phone will keep ringing.

Tidal Wave

Take about 20 (or more) paper or plastic cups, place
them on the victim's desk and fill them with water. Then take a stapler
and staple them all together. You can also put the cups on the floor
blocking their door, or just about anywhere.

Fresh and Queasy

Go to a dollar store and buy alot of different scented air fresheners (for the car or home). Hide them in the victim's office. Tape them to the bottom of drawers, tables
and chairs, and behind furniture that is up against a wall, etc. The mesh of smells will be overpowering!

Switcheroo

Remove your victim's desk chair and replace it with a bench from outside (the heavier the better!).

Is It My Turn?

Have a multi-stall restroom at work? Just round up enough shoes and pants so you have one set for each stall. Put them in place in front of each toilet, stuffing the pant
legs to make them look realistic. Lock the doors and crawl out. See how long it will take people to figure out what the big hold-up is!

Just One Please

Take all of the victim's paperclips and hook them
together in one long string.

While You Were Out

Leave a phone message for the victim that says that a "Mr. Lee Muhr" called and wants to be called back. Then give the phone number of the zoo. Iowa's Blank Park Zoo has
set up special phone numbers for this: Ms. Diane Osaurus at 515-974-2670; Mr. Lee Muhr at 515-974-2671; Ms. Cassie Warrie at 515-974-2672; Mr. Al Gator at 515-974-2673.

Dude, Where's My Car?

Borrow your victim's car keys and make a duplicate. Then, every day or so, move the car a few parking spaces over, or turn it around so it's parked backwards in the space.
Eventually start moving it to another part of the lot altogether. Classic.
